The Audi EA835 6-cylinder V-engine range was produced from 1990 to 2008 and was installed on the most popular concern models of its time, such as the A4, A6 and A8. There are three generations of engines: with a 12-valve cylinder head, a 30-valve cylinder head and an aluminum block.
At the very end of 1990, the company’s V6 power unit debuted on the Audi 100 model. The first was a 2.8-liter engine, and a year later there was a 2.6-liter with a smaller piston stroke.
These engines were created from a V8 engine, so they have a typical 90° camber. The cylinder block in the engine is cast iron, with a pair of aluminum cylinder heads and hydraulic lifters. The timing belt drives 2 camshafts and controls a dozen valves respectively.
There were only two engines in this series, although in a number of markets they had other indices:
In 1995, DOHC versions of V6 units appeared, their cylinder heads had 5 valves per cylinder. The new cylinder heads required a complication of the timing and chains between the camshafts were added to the belt.
And the rest of the changes were evolutionary, but the number of models has seriously increased: power units with a volume of 2.4 liters, 2.8 liters, and also 2.7-liter turbo engines were offered.
There were a lot of modifications in this series, here we list only the most famous of them:
In 2000, the company’s latest V6 units with multipoint fuel injection appeared. This line of engines was distinguished by aluminum cylinder blocks with an extremely controversial reputation.
Another innovation was phase shifters on the intake and exhaust camshafts. There were not so many modifications this time, we only know 3.0-liter engines:
Since 2006, these units have begun to replace FSI direct injection engines of the EA837 family.
The 2.6-liter gasoline V6 engine of the Audi ABC was produced by the company from 1992 to 1997 and was installed on such popular concern models of its time as 80, 100, A4 and A6 C4. There is a derated version of this power unit under its own ACZ index.
The 2.8-liter Audi AAH 2.8 V6 gasoline engine was produced by the concern from 1990 to 1997 and was installed on the most popular models of the German company such as 80, 100, A4, A6 or A8. This power unit was known in some markets under a completely different AFC index.
The 2.4-liter Audi ALF 2.4 V6 engine was produced at the concern’s factories from 1997 to 2000 and was installed on the company’s most popular models of its time: A4 B5, and also A6 C5. This power unit has many analogues under other indices: AGA, APS, AML and ARJ.
The company assembled the 2.4-liter injection engine Audi BDV 2.4 V6 from 2001 to 2005 and installed only two, but very massive models of the concern of that time: A4 B6 and A6 C5. This power unit is essentially an environmentally improved analogue of the APS or ARJ motor.
The 2.7-liter bi-turbo V6 Audi ARE engine was produced by the concern only from 2000 to 2005 and was installed on the Audi A6 in the C5 body, as well as its popular Allroad Quattro modification. There is an updated modification of such a unit under its own BES index.
The 2.8-liter 30-valve Audi ACK 2.8 V6 engine was assembled by the concern from 1995 to 1998 and was installed on such popular models as the A4 in the back of the B5, and also the A6 in the back of the C4 or C5. This motor has many analogues with minor differences, such as …
The 2.8-liter gasoline engine Audi ALG 2.8 V6 was produced by the company from 1997 to 2000 and was installed on the most popular models of the concern of its time: A4 B5, A6 C5 and A8 D2. This power unit replaced a similar ACK and gave way to the motor under the APR index.
The 3.0-liter Audi BBJ 3.0 V6 engine was produced by the German concern from 2000 to 2008 and was installed on many popular models of the company of its time, such as the A4, A6 and A8. This power unit was not offered on the European market, its analogue ASN was present there.
The company assembled the 3.0-liter 30-valve Audi ASN 3.0 V6 engine from 2000 to 2005 and installed it on advanced modifications of a number of popular models, such as the A4, A6 and A8. There was a derated version of the unit for developing countries under the BBJ index.
